SHOE-LAST.

Intented Aug. 24, 1920.

Application filed October 1, 1918. Serial No. 256,443.

the manufacture This invention relates to novel of boots and shoes andcomprises a last for use in the manufacture of such articles.

One of the principal objections to shoes of the McKay and turn types isthe presence of stitches or other fastenings in the inside of the shoe,where they cause discomfort to the wearer and mar the appearance of theshoe The use of an inside slip sole has not en-- tirely avoided thisobjection, and attempts have been made to position the fastenlngs in achannel formed in the upper face of the Great difliculty in keeping thechannel flap in temper has been experienced, however, channel properlyand smoothly after the attachment of the sole.

It has been proposed broadly to treat a part of the shoe lying next tothe last, in particular a channel flap, assembled on the last, to insurethat it w ll be in temper for subsequent operations, and in particularto keep in temper the turned up channel flap of an insole such as abovedescribed during the lasting and sole laying operations, so that it willbe in properv condition to belaid and cemented smoothly after the soleattaching operation. u

A last adapted for the practice of the described process, arranged witha cavity in the bottom to hold means, such as a dampened tempering pad,for treatmga part of a shoe (in particular as herein illustrated thechannel fiap) while. the shoe remains on the last, has also beenproposed. The present invention provides a last .with a cavity havingwaterproof walls in order to prevent damage to the body of the last bymoisture,

the cavitybeing adapted to hold a dampened tempering pad; Preferably,also, the narrow outside rim of the cavity is formed of some toughmaterial, such as fiber, to enable it to withstand repeated tacking.

, the

with consequent failure to close the after the shoe is These and otherfeatures of the invention 'will be understoodfrom the followingvdetised.

In the drawings,

Figure ,1 shows a perspective of the last.-

Fig. 2 is a cross section showing the step of lasting the upper.

Flg. 3 is a cross section of the completed shoe, and v f,

Fig. 4 shows the insole.

The main ,bjody 10 of the last may be 0 any desired ,ztype, as forexample, solid, block, or hinge.- The bottom of the last is formedpreferably of some waterproof material 12, as fiber, and contains alongitudinal depression 14. In the last shown this depression extendsfrom near the ti to the metal heel plate 16. It is not as wide as thebottom of thelast, and leaves a strip 18 ,in

position "of the usual last bottom approximately %{inch wide around theedge of the tread face. The strip 18 may be made integral withthewaterproof last bottom 12,

' or 'may be removable, if desired, as indicated in dotted lines in Fig.2, and will preferably be formed of material adapted to permit tacking.A dampenedpad' 20, of spongy material, as for example felt, is placed inthe de ression 14.

n accordance with my invention 'the last is used as follows in themanufacture of McKay shoes I An insole 22 is channeled in its upper surface, as. at 24. This channel runs preferably on each side of the insolefrom the heel 96- breast portion to a point nearthe toe tip.- Thechannel is preferably not run around the toe ti for the reason that suchrocedure wiii weaken the insole too muc at this point, the insole stockused in shoes of 100 this type being often very inferior; and for thefurther reason that a channel flap at the extreme tip would interferewith the "last pulling.

The insole is applied to the last with the 106 channel flaps turned backinto the depression 14 where the dam ened pad 20 keeps them in propertemper seeFig. 2). At t e same time, the waterproof bottom preventsinjury to the wooden body of the last from 110 the continuous presenceof the dampened pad 20. The upper 26 is then lasted and is preferablycemented to the insole 22, a few lasting tacks 28 being. driven to holdit until the cement has set, and removed before the last pulling. Thefiber rim 18 has been found to permit repeated tacking much moreadvantageously than wood would dot Such treatment of a wooden rim ofsuchsmall width would soon shatter it. The last is readily removedbecause of the unchann'eled plate at the toe tip and the outsole maythen be attached in any desired manner, the fastenings shown or stitches30 being placed in the channel, after which the tempered flap ma becemented down, having a flat smooth lnsole except at the toe tip wherethe foot is not in contact with the insole.

I do not claim broadly a last having a cavity constructed and arrangedto hold means for tempering a ortion of a shoe on a last, nor do clalm te disclosed method of manufacturing shoes com rising maintaining aninternal channel ap in temper while the shoe is on a last, since thesematters are not my invention.

Having described my invention, what I claim as new and desire to securebyLetters Patent of the United Statesis 2-- 1. A shoe last havingawaterproof bottom and having a cavity in said bottom con- StIlCtGd andarranged to hold a moistened 2. A shoe last having a cavity in itsbottom constructed and arranged to receive a channel flap, the rim ofthe bottom around the cavity being composed 0t fiber.

In testimony whereof I have signed my name to this specification.
